Application flied May 26, 1915. Serial No. 80,617.

To ([22 whom it may concern Be it known that 1, JOHN F. Snxrmi coma. in the county of Pierce and State of ashington have invented a new and useinticreeping Device for Railroads, of

h the following is a specification.

i iis invention relates to an improvement in anti-creeping devices for railways, and

w the object is to provide means that can be applied to a tie plate for engaging a rail for holding the rail against movement in either direction.

A further object is to provide a gripping eviee with teeth to be driven into and enthe side edge of the base flange of a ail being held in such engagement by a key. is to provide a fastening means which can he A further object of the invention manufactured at a small cost and operated with ease.

The invention consists of certain novel features of construction and combinations of parts which will be hereinafter described and pointed out in the claim.

Tt is understood that many slight, changes may be made in the form and arrangement of the several parts described without departing from the spirit and scope of the invention, and hence I ited to the exact construction as herein set forth.

Tn the accompanying drawings,Figure It is a view in elevation showing a rail in section. Fig. 2 is a longitudinal vertical sectional view. Fig. 8 is a top plan view with a portion broken away to disclose the operation of the gripping member. Fig. l is a bottom plan view. Fig. 5 is a perspective view of the gripping member. Fig. 6 is a perspective view of a modified forn of gripping member. Fig.7 1s a perspective view of another form of gripping member.

- A. represents the tie, and mounted upon the tie is a tie plate B. Mounted upon the tie plate B is a rail C. One edge of the base flange l of the rail is received in a recess 2 in the jaw 3 of the tie plate. The latter is preferably rectangular in form.

Projections a are formed on the tie plate andiii aiinement with the jaw 3 for engagement with one edge or side of the base flange of the rail. The diametrically opposite side or edge of the base flange of the rail is engaged by a movable gripping member 5.

do not wish to be liin- The working face of the gripping member is provided with teeth 6 which extend vertically fromthe base of the gripping mem her and then at an acute angle forming an over-hanging portion which extends over the base flange. A housing 7 is formed on the tie plate which is provided with a longi-- tudiiial slot 8 in which the gripping menr her 5 slides. The housing is open at each end and serves as a guide for said. member. i transverse slot 9 is formed through the housing in which a wedge 01 key 10 is received. The wedge or key 10 is adapted to engage a shoulder 11 which is formed onthe gripping member by reducing the rear portion of the gripping member.

A tapered or beveled surface 12 is formed in the housing along one wall of the transverse slot 9 which is. adapted to be engaged by the beveled or tapering surface 13 of the wedge or key 10 so that as the wedge or key 10 is driven or forced through the slot 9 the straight edge of the wedge or key will engage the shoulder 11 and force the gripping member into place and in contact with the rail for locking the rail againstinovement in either direction longitudinally.

A. recess or groove ll is formed in the body of the tie plate which extends beneath the base flange l of the rail said recess 6X' tending from the outer end of the plate inwardly beyond the inner end of the housing. The gripping. member 5 moves in this groove permitting the gripping member to be forced into engagement with the entire edge of the base flange l of the rail fromtop to bottom thereof, so that the teeth may be driven into the edge by striking the rear terminal of the gripping member with a hammer or maul, and causing the upper portion of the grippingmember to overhang the base flange. The wedge or key 10 can then be driven through the transverse slot 9 and confine the gripping member in rigid contact with the base flange 1. The tie plate B will be fastened to the tie by means of spikes which will pass through openings 15. The projections a are arranged at one side of one pair of these openings. Bits or ridges 16 are formed on the lower surface of the tie plate, preferably of herring bone shape, although any other suitable design may be adapted, and are embedded into the tie for strengthening and fastening the tie plate against movement.

gripping .within the housing 7.

In the modification shown in Fig. 6 the member 5 is provided with a transverse slot 17 through which the wedge 10 ma pass.

The gripping member disclosed in Fig. 7 is of a size which will be completely housed The teeth of the grip ing members will penetrate and embed themselves in the edges of the base flange of a rail and will prevent the rail from moving longitudinall These gripping members will be sutiicient to prevent the longitudinal movement of the rail unless some force should cause the gripping members to be torn from the rail and thereby tear a portion from the base of the rail.

From the foregoing it will be seen that I have provided a tie plate which ma v be maintained upon the rail, and a locking means which will confine the rail upon the tie plate, so that it will be impos ible for the rail to move longitudinally or laterally of the tie plate.

X0 claim is made in this application to the plate or support having an integral housing, and a recess in the upper face of the plate, which extends beyond the housing to a point below the base flange of a rail, when the latter is in place and a gripping member tor the rail located in the housing, and mo Table in the said recess,

' said gripping member having teeth proent Ofiice October lth, 1915.

hat is claimed 1s In a rail tastemng, a plate of substantiallv rectangular tormhaving spike openings at the corners, projections formed on the plate contiguous to two of said spikeopenings and in substantial alinement with the inner walls of said openings,- an integral jaw provided on the plate between the said projections and in longitudinal alinement with said projections, a guide or housing provided on the tie plate diametrically opposite the said jaw, said guide or housing having its inner end open, a movable gripping member mounted in the guide or housing, and means for moving the movable gripping member through the opening of the guide or housing into engagement with the rail.

In testimony that I claim the foregoing as my owm I have hereto atfixed my signature in the presence of two witnesses.
